Request Builder: 'UNKNOWN' Error

Bugs & Features
1

In the request builder I get the pop-up that says “Something went wrong - UNKNOWN”.
It is challenging to find out what is wrong in the script.
The developer tools reflect a HTTP 500 error.

The request is a data fusion request of BYOC PlanetScope data, and has two date ranges. See sh-py below.

Your assistance would be greatly appreciated.

Hi @jens.hiestermann ,

It seems to me that there is no need to use data fusion in your case as you’re requesting data from the same BYOC collection. You could use mosaicking ORBIT and preProcessScenes to get the values for “before” and “after”, then you can calculate the difference and return it.

Please take a look at the following request as an example:

curl -X POST https://services.sentinel-hub.com/api/v1/process \
 -H 'Content-Type: application/json' \
 -H 'Authorization: Bearer <token>' \
 -d '{

      ]
    },
    "data": [

Thank you @chung.horng, I wasn’t aware that is possible. Let me give it a go.
